Solar photovoltaic and wind power in Greece

The high energy cost for power supply to the Greek islands, as well as the favourable solar and wind conditions, led to the utilisation of these local energy sources for power generation. On the island of Kythnos, the first wind park of a capacity of 100 kW was installed as well as a 100 kWp solar photovoltaic plant with storage facility. Both plants are grid-connected for parallel operation with the existing diesel power station. Also, a stand-alone 50 kWp solar photovoltaic plant was installed in Aghia Roumeli, Crete, to supply the community. The experience gained from the design, installation and operation of the above projects led to the implementation of some demonstration projects, and to a five-year programme in solar and wind energy for power generation. Existing data and results from the islands favour a large-scale wind usage for oil saving. Small stand-alone PV plants for small systems are cost-effective. Hybrid solar and wind power systems for small islands are realisable.
